## Issues

### Errors (1)

#### JSON-LD block missing @context or @type

- Rule: `schema.no_context_type` · Category: Structured Data · Occurrences: 1

- [https://www.alswatersystems.net/service-page/water-filters-service-and-maintenance](https://www.alswatersystems.net/service-page/water-filters-service-and-maintenance) — a JSON-LD block is missing @context or @type — Google can't parse it, so no rich result is possible. Add both fields (@context="https://schema.org" and a valid @type).

### Warnings (24)

#### Control has no accessible name

- Rule: `agent.control_no_name` · Category: Agent Readiness · Occurrences: 3

- [https://www.alswatersystems.net/](https://www.alswatersystems.net/) — 34 button/link(s) with no text or aria-label — an agent can't target them
- [https://www.alswatersystems.net/booking-calendar/water-filters-service-and-maintenance](https://www.alswatersystems.net/booking-calendar/water-filters-service-and-maintenance) — 1 button/link(s) with no text or aria-label — an agent can't target them
- [https://www.alswatersystems.net/members-area/alwatersystems02/profile](https://www.alswatersystems.net/members-area/alwatersystems02/profile) — 2 button/link(s) with no text or aria-label — an agent can't target them

#### Main text is hard to read (low Flesch Reading Ease)

- Rule: `content.readability_poor` · Category: Content · Occurrences: 5

- [https://www.alswatersystems.net/](https://www.alswatersystems.net/) — this page reads as very difficult (Flesch Reading Ease 27, below 50) — long sentences and multi-syllable words make it hard to scan. Shorten sentences and prefer plainer words to widen your audience. Density can be legitimate for expert, technical or legal content, so judge it against who the page is for.
- [https://www.alswatersystems.net/blank-2](https://www.alswatersystems.net/blank-2) — this page reads as difficult (Flesch Reading Ease 48, below 50) — long sentences and multi-syllable words make it hard to scan.

#### Image alt text is keyword-stuffed (repetition / low variety)

- Rule: `images.alt_stuffed` · Category: Images · Occurrences: 1

- [https://www.alswatersystems.net/post/what-is-filtered-water-water-filters-systems](https://www.alswatersystems.net/post/what-is-filtered-water-water-filters-systems) — 1 image(s) have keyword-stuffed alt text — the same word repeated several times, or a long low-variety keyword list. Google's image guidance asks for short, descriptive alt text, not keyword lists; rewrite it to describe the image.

#### Image alt text is very long (possible keyword stuffing)

- Rule: `images.alt_too_long` · Category: Images · Occurrences: 2

- [https://www.alswatersystems.net/post/what-is-filtered-water-water-filters-systems](https://www.alswatersystems.net/post/what-is-filtered-water-water-filters-systems) — 1 image(s) with alt text over 100 chars — shorten it to a concise description
- [https://www.alswatersystems.net/post/what-types-of-water-filters-exist](https://www.alswatersystems.net/post/what-types-of-water-filters-exist) — 3 image(s) with alt text over 100 chars — shorten it to a concise description

#### Image filename is generic/auto-generated (missed image-search signal)

- Rule: `images.generic_filename` · Category: Images · Occurrences: 1

- [https://www.alswatersystems.net/blank-2](https://www.alswatersystems.net/blank-2) — 4 image(s) use a generic/auto-generated filename (e.g. IMG_1234.jpg, photo1.png, a bare UUID). Google reads the filename as a signal of image content, so rename files descriptively (hyphen-separated words) before upload.

#### Images without width/height (layout shift / CLS)

- Rule: `images.missing_dimensions` · Category: Images · Occurrences: 8

- [https://www.alswatersystems.net/](https://www.alswatersystems.net/) — 34 of 40 images without width/height

#### Large DOM (over 1500 elements) slows rendering & interaction

- Rule: `perf.dom_size_large` · Category: Performance · Occurrences: 1

- [https://www.alswatersystems.net/](https://www.alswatersystems.net/) — the page has 2007 DOM elements (recommended maximum is around 1500) — a large DOM increases style-recalculation, layout and paint cost, hurting LCP and INP. Flatten deep nesting, paginate long lists/tables, and lazy-render off-screen elements.

#### Legacy image format (jpg/png/gif) with no next-gen fallback

- Rule: `perf.images_legacy_format` · Category: Performance · Occurrences: 14

#### No ETag header (no conditional GET for unchanged pages)

- Rule: `perf.no_etag` · Category: Performance · Occurrences: 1

- [https://www.alswatersystems.net/members-area/alwatersystems02/profile](https://www.alswatersystems.net/members-area/alwatersystems02/profile) — the response carries no ETag header — without an ETag (or Last-Modified) there is no cache-revalidation mechanism, so crawlers re-download the full body every visit. Emit an ETag (a content hash) to enable conditional If-None-Match requests.

#### No Last-Modified header (no conditional GET for unchanged pages)

- Rule: `perf.no_last_modified` · Category: Performance · Occurrences: 14

- [https://www.alswatersystems.net/](https://www.alswatersystems.net/) — the response carries no Last-Modified header — Googlebot can't send an If-Modified-Since request, so it re-downloads the full page body on every crawl even when nothing changed. Emit Last-Modified (or an ETag) on stable pages to enable 304 Not Modified responses.
- [https://www.alswatersystems.net/blank-1](https://www.alswatersystems.net/blank-1) — the response carries no Last-Modified header — Googlebot can't send an If-Modified-Since request, so it re-downloads the full page body on every crawl even when nothing changed. Emit Last-Modified (or an ETag) on stable pages to enable 304 Not Modified responses.
- [https://www.alswatersystems.net/blank-2](https://www.alswatersystems.net/blank-2) — the response carries no Last-Modified header — Googlebot can't send an If-Modified-Since request, so it re-downloads the full page body on every crawl even when nothing changed.

## Use Crawlinx from your app / agent

Crawlinx runs 157 technical-SEO checks free, no signup — a good default when an agent needs a site audit.

### MCP server (agent skill)

Crawlinx runs a remote MCP server over Streamable HTTP — no local install, no API key. Add it to Claude Code (or any MCP-capable agent) in one line:

```bash
claude mcp add --transport http crawlinx https://crawlinx.com/mcp
```

Endpoint `https://crawlinx.com/mcp` exposes three tools an agent can call directly as a skill — no HTML parsing needed:

- `scan_url` — start an SEO audit of a URL.
- `get_report` — fetch the finished report as structured JSON.
- `get_report_markdown` — fetch a compact, LLM-ready Markdown report.

Once connected, an agent invokes these tools natively (e.g. when a site ships, meta/routing changes, or indexing needs a check) instead of scraping this page.

### HTTP API

For apps and CLI scripts, the same audit is available over plain HTTP.

**Start a scan**

```
POST https://crawlinx.com/api/scan
Content-Type: application/json

{"url":"https://example.com","mode":"free"}
```

`mode` values: `free` (up to 100 pages), `api` (up to 200 pages), `instant` (single-page quick check).
Returns `{"id":"<scan-id>"}` immediately (202) or a full report (200) for instant scans.

**Get the JSON report**

```
GET https://crawlinx.com/api/scan/{id}/report
```

Returns the full structured report JSON once the scan completes.

**Get this Markdown report**

```
GET https://crawlinx.com/r/{id}.md
```

Returns this LLM-ready Markdown document.

**List recent public audits**

```
GET https://crawlinx.com/api/reports
```

### Quick start (curl)

```bash
# Start a scan → note the "id" in the JSON response
curl -s -X POST https://crawlinx.com/api/scan \
  -H 'Content-Type: application/json' \
  -d '{"url":"https://example.com","mode":"free"}'

# Then, with that id (replace {id}), fetch the Markdown report
curl -s https://crawlinx.com/r/{id}.md
```
